State 2 purposes of the File Server do for us (It’s role think of 2 different things it can do)
Stores all available programs
Stores a list of all the users (usernames & passwords)
List 4 peripherals
Any input or output device or backing storage device
What is the benefit of sharing peripherals
It is less expensive i.e. 1 printer
Insert 2 pictures of Input Devices & label them
Any suitable i.e. keyboard, mouse, digital camera etc.

[Type text]
14. Explain in detail the CPU, RAM and ROM (as fully as possible)
CPU – Is the Brain of the computer which processes the information
RAM – A program or file is loaded into RAM
It is a temporary memory
The contents of RAM are erased when the computer is switched off
The contents of RAM can be changed
ROM – it is permanent memory
The Systems software is stored on the ROM chip
The contents of ROM are not erased when the computer is switched off
You cannot add or change the information in ROM
Protected from viruses
15. What is the purpose of the Motherboard
Holds the hardware that deals with the processing of the data
OR Holds the CPU and Main Memory (RAM & ROM)
16. Ram and Rom are types of computer
memory
(insert the missing word)
NOW SAVE YOUR WORK
17. Explain what happened to your document when you just saved it. (Where was it & what happened to it)
It was loaded in RAM to start and moved to Backing Storage.
It is still held in Ram as it remains open but it will need to be resaved after changing the document
18. Insert 4 Pictures of backing storage devices & label them
If it says media it would be tape not tape drive (only drive if devices)
Any suitable disc or tape drive
19. Which backing storage device is used in school for Back-ups
Tape Drive
20. Which backing storage device would you use for Back-ups
